70mm Imax is a *film* projection format. It uses a special film that is twice as big as 35mm which used to the the “standard” format before movies moved to digital exhibition. So there’s a lot higher resolution than a standard (film) projection, and it can be projected larger . It has higher audio quality than standard 35mm projection had, as there was more space for surround soundtracks to be encoded. 70mm also is a different aspect ratio size - 1.43:1 so the picture is “more square” or “less rectangular” than most theatrical films that are either 1.85:1 (flat) or 2.39:1 (scope).
70mm was the size it was so it could completely fill “classic” Imax screens which are *much* larger than traditional movie theatre screens (and were also “more square” to better fill an entire wall).
For films like “Dark Night Returns” and “Interstellar” only *some* of the material in the film was filmed with Imax 70mm cameras - so parts of the film would fill the *entire* screen, and other parts would be letter-boxed with black bars to look more like a traditional (rectangular) movie screen.
“Digital IMAX” on the other hand is *projection* format - a proprietary system for projecting digital movies (from a computer file, not a reel of physical film) using two linked digital projectors. This allows a pictures that is brighter and (possibly) sharper and/or screens usually (but not always) slightly bigger than what’s commonly available in most multiplexes. Digital IMAX is usually an improvement over a regular 2K projection - but not the large difference that 70mm was from 35mm.
Films that actually shoot scenes in 70mm IMAX are extremely rare as the equipment is extremely heavy, loud, expensive, and can only record for 90 seconds at a time. As the number of theatres that can project 70mm is rapidly decreasing, this is a technology that’s sadly probably on it’s way out.
